The smiths spend 8% of their budget on entertainment. their total budget this year is 2000$ more than last year, and this year they plan to spend 3,840 on entertainment. what was their total budget this year?

$3,582.8

Step-by-step explanation:

3,840 x 8% = 307.2

3,840 - 307.2 = $3,582.8

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
